- The evidence locker. Every case opens with 6 exhibits — documents, messages, records. Review at least 4 of 6 before the accusation unlocks. Every tell you need is in there; nothing is withheld.
- The suspects. Three people, each with three interview questions on the record. Their answers are fixed — read them carefully, because someone is shading the truth.
- The accusation. Three questions, one point each: what happened, who did it, and the safest move. Record your confidence (1–5) before the reveal — it doesn't change your score, but honest detectives track it.
- The verdict. Scored out of 3, with a line-by-line breakdown of where you were right and where the trail went cold. A perfect 3/3 stamps the file Case Closed · Clean Solve.
Simple and fixed. Three questions per case, one point each — 3 points per case. The verdict screen walks you through every question: +1 for a correct call, +0 for a miss, with the reason why. No partial credit, no trick questions.
Replay any case as often as you like. Your best score per case is kept — replays can't farm XP, and a bad replay can't erase your best solve.
XP is earned two ways:
- Case points × 10. Each of your best case scores earns 10 XP per point. Improving a best score banks only the difference — replaying a 2/3 into a 3/3 earns +10 XP, not +30.
- Daily reveals × 5. Revealing the answer on today's Daily Dossier earns +5 XP, once per day.
Your total XP sets your rank. There are 8 of them:
ROOKIE → LEGEND
Rookie — 0 XP
Beat Cop — 20 XP
Gumshoe — 50 XP
Investigator — 90 XP
Senior Detective — 140 XP
Inspector — 200 XP
Chief Inspector — 300 XP
Legend — 450 XP
A fresh bite-size mystery lands every morning. Read the file, study the clues, and reveal the answer to bank that day's streak. Rules:
- One per day. Revealing the answer banks one streak day and +5 XP. Opening it twice in one day changes nothing.
- Consecutive days only. Reveal day after day and the streak grows. Skip a day and it resets to 1 — the file waits for no one.
- Milestones. 7 days earns Week on the beat, 14 days earns Fortnight file, 30 days earns Month of nights.
- The 30-file rotation, disclosed. The daily file is drawn from a fixed 30-file library in rotation — after day 30 the cycle repeats, so a case you've already solved may come back around. Today's pick is today's pick; the archive holds the recent past.
The archive keeps the last 14 days of dossiers, for reading and catching up. The rule is strict and public: revealing an archive file banks no streak and no XP — it's for the love of the game, not the record. Only today's dossier keeps your streak alive.
Everything you do here is stored in this browser only — no accounts, no email, nothing leaves your device. There is no leaderboard, and we never invent other players' scores. Your detective profile is read straight from your own local storage.
Every verdict screen includes a one-tap result card — your score, the case name, and a verdict line you can paste anywhere. Your detective profile has a full record card too: rank, XP, cases closed, and streak.
New full cases are added periodically. The Daily Dossier runs every day regardless — there's always a fresh file to open.
